About This Trend
Grand Slam refers to a term used in golf to describe when a player wins all four major tournaments, which include the Masters, U.S. Open, British Open, and PGA Championship, over the course of their careers.
The term Grand Slam is trending due to Rory McIlroy's current attempt to complete the career Grand Slam at the Masters, a feat that would make him the first player in 90 years to achieve this at Augusta National.
